INSTALLATION INSTRUCTIONS

General

These furnaces are shipped with materials to assist in proper
furnace installation. These materials are shipped in the main
blower compartment.
See Table 1 for loose parts bag contents.
This furnace must:
S
be installed so the electrical components are
protected from water.
S
not be installed directly on any combustible material
other than wood flooring (refer to SAFETY
CONSIDERATIONS).
S
be located close to the chimney or vent and attached
to an air distribution system. Refer to Air Ducts
section.
S
be provided ample space for servicing and cleaning.
Always comply with minimum fire protection
clearances shown in Table 2 or on the furnace
clearance to combustible construction label.

CAUTION
!
PERSONAL INJURY AND/OR PROPERTY
DAMAGE HAZARD
Improper use or installation of this furnace may result
in premature furnace component failure. Unless
otherwise prohibited, this gas furnace may be used
for heating buildings under construction provided that:
−The furnace is permanently installed with all
electrical wiring, piping, venting and ducting installed
according to these installation instructions. A return
air duct is provided, sealed to the furnace casing, and
terminated outside the space containing the furnace.
This prevents a negative pressure condition as
created by the circulating air blower, causing a flame
rollout and/or drawing combustion products into the
structure.
−The furnace is controlled by a thermostat. It may not
be "hot wired" to provide heat continuously to the
structure without thermostatic control.
−Clean outside air is provided for combustion. This is
to minimize the corrosive effects of adhesives,
sealers and other construction materials. It also
prevents the entrainment of drywall dust into
combustion air, which can cause fouling and plugging
of furnace components.
−The temperature of the return air to the furnace is
maintained between 55_F (13_C) and 80_F (27_C),
with no evening setback or shutdown. The use of the
furnace while the structure is under construction is
deemed to be intermittent
installation instructions.
−The air temperature rise is within the rated rise
range on the furnace rating plate, and the gas input
rate has been set to the nameplate value.
−The filters used to clean the circulating air during the
construction process must be either changed or
thoroughly cleaned prior to occupancy.
−The furnace, ductwork and filters are cleaned as
necessary to remove drywall dust and construction
debris from all HVAC system components after
construction is completed.
−Verify proper furnace operating conditions including
ignition, gas input rate, air temperature rise, and
venting according to these installation instructions.

WARNING
!
CARBON MONOXIDE
COMPONENT DAMAGE HAZARD
Failure to follow this warning could result in personal
injury or death and unit component damage.
Corrosive or contaminated air may cause failure of
parts containing flue gas, which could leak into the
living space. Air for combustion must not be
contaminated by halogen compounds, which include
fluoride, chloride, bromide,
elements can corrode heat exchangers and shorten
furnace life. Air contaminants are found in aerosol
sprays, detergents, bleaches,
salts, air fresheners, and other household products.
Do not install furnace in a corrosive or contaminated
atmosphere. Make sure
circulating air requirements are met, in addition to all
local codes and ordinances.
The following types of furnace installations may require
OUTDOOR AIR for combustion due to chemical exposures:
S
Commercial buildings
S
Buildings with indoor pools
S
Laundry rooms
S
Hobby or craft rooms
S
Chemical storage areas
If air is exposed to the following substances, it should not be
used for combustion air, and outdoor air may be required for
combustion:
S
Permanent wave solutions
S
Chlorinated waxes and cleaners
S
Chlorine based swimming pool chemicals
S
Water softening chemicals
S
De−icing salts or chemicals
S
Carbon tetrachloride
S
Halogen type refrigerants
S
Cleaning solvents (such as perchloroethylene)
S
Printing inks, paint removers, varnishes, etc.
S
Hydrochloric acid
S
Cements and glues
S
Antistatic fabric softeners for clothes dryers
S
Masonry acid washing materials
All fuel−burning equipment must be supplied with air for fuel
combustion. Sufficient air must be provided to avoid negative
pressure in the equipment room or space. A positive seal must
be made between the furnace cabinet and the return−air duct
to prevent pulling air from the burner area.
WARNING
!
FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
When the furnace is installed in a residential garage,
the burners and ignition sources must be located at
least 18 in. (457 mm) above the floor. The furnace
must be located or protected to avoid damage by
vehicles. When the furnace is installed in a public
garage, airplane hanger, or other building having a
hazardous atmosphere,
installed in accordance with
NFPA 54/ANSI Z223.1 or CAN/CSA B149.2. (See
Figure 5.)
